Hydroxyapatite (HA) was implanted in bone defects after curettage of benign bone tumors, including among others seven solitary bone cysts, and six giant cell tumors. Seventeen patients ranging in age from 6-69 years, had 18 implantations. Ten cases were only implanted by HA for small lesions or for lesions in children. Eight cases had both HA and autograft inplantations for large lesions affecting pathological fractures or weight-bearing lesions. Postoperative courses were satisfactory and complete healing was achieved in all cases with only one complication. The duration of follow-up ranged from 2-30 months (mean: 13 months).HA is therefore very useful for filling up bone defects after curettage of benign bone tumors from the point of biological safety, bone formation, availability and ease of use.
